These calls could be crucial for you in business or something else. In these cases, IoT reroutes incoming calls to your mobile phone number when traveling overseas from your US-based phone or your home landline. IoT sim offers the option to hold the ring in voice mail if you are unavailable at that number, and IoT sim notifies you by sending you an SMS text message. Just calls that our system forwards to your new mobile number is charged, and the cost is only half of what roaming would be.
